In order to be able to properly support architecture that want/need to support TLB range invalidation, we need to change the flush_tlb_range() argument from a vm_area_struct to an mm_struct because the range might very well extend past one VMA, or not have a VMA at all. There are two mmu_gather cases to consider: unmap_region() tlb_gather_mmu() unmap_vmas() for (; vma; vma = vma->vm_next) unmao_page_range() tlb_start_vma() -> flush cache range zap_*_range() ptep_get_and_clear_full() -> batch/track external tlbs tlb_remove_tlb_entry() -> batch/track external tlbs tlb_remove_page() -> track range/batch page tlb_end_vma() free_pgtables() while (vma) unlink_*_vma() free_*_range() *_free_tlb() -> track tlb range tlb_finish_mmu() -> flush everything free vmas and: shift_arg_pages() tlb_gather_mmu() free_*_range() *_free_tlb() -> track tlb range tlb_finish_mmu() -> flush things There are various reasons that we need to flush TLBs _after_ freeing the page-tables themselves. For some architectures (x86 among others) this serializes against (both hardware and software) page table walkers like gup_fast(). For others (ARM) this is (also) needed to evict stale page-table caches - ARM LPAE mode apparently caches page tables and concurrent hardware walkers could re-populate these caches if the final tlb flush were to be from tlb_end_vma() since an concurrent walk could still be in progress. Therefore we need to track the range over all VMAs and the freeing of the page-tables themselves. This means we cannot use a VMA argument to the flush the TLB range. Mostly architectures only used the ->vm_mm argument anyway, and conversion is straight forward and removes numerous fake vma instrances created just to pass an mm pointer. The exceptions are ARM and TILE, both of which also look at ->vm_flags, ARM uses this to optimize TBL flushes for Harvard style MMUs that have independent I-TLB ops. The taken conversion is rather ugly (because I can't write ARM asm) and creates a fake VMA with VM_EXEC set so that it effectively always flushes the I-TLBs and thus looses the optimization. TILE uses vm_flags to check for VM_EXEC in order to flush I-cache, but also checks VM_HUGETLB. Arguably it shouldn't flush I-cache here and we can use things like update_mmu_cache() to solve this. As for the HUGETLB case, we can simply flush both at a small penalty. The current conversion does all three, I-cache, TLB and HUGETLB.
